LASTING-MACl-HNE.

SPECIFICATION forming part of Letters Patent No. 597,247, dated January 11, 1898. Application i'iled April 80, 1897. Serial No. 634,612. (No model.)

construction and relative arrangement of parts clearly illustrated upon the accompanying drawings, fully described in the following speciiication, and particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, and to the letters and iigures marked thereon, forming a part of this speciication, the same letters and figures desigmating the same parts and features, as the .coupler for the Wipers.

case may be, wherever they occur.

Of the drawings, Figure l represents in side elevation a machine embodying my invention. Fig. 2 represents in plan View the head carrying the Wipers for the heel end of the last. Fig. 3 represents a side elevation of the same. elevation thereof. Fig. 5 represents the saine in plan View with the top plate removed, so as to expose the Wipers. Fig. 6 represents a cross-section on the line 6 6 of Fig. Figs. 7, S, 9, and l0 are views siinilar to Figs. 2, 8, 4, and 5 and showing the head andthe Wipers for the toe end of the last. Figs. Vl0, 10b, and lOc are detail views illustrating the disk Fig. ll represents a longitudinal section through the head, taken on the line ll of Fig. '7. Fig. 12 represents the heads in plan View, partially in section, with the top plates and Wipers removed, so as to show the band and its carriers for clamping the upper to the last. Fig. 13 represents the band and carriers at the toe end when in their operative positions. Fig. le is a perspective View of the band and carriers detached. Fig. l5 represents the band as being lformed in tivo independent parts. Figs. lb to l5), inclusive, show other forms of Wipers.

Referring to the drawings, which show the forni of iny invention which l have selected Fig. fi represents a rear end for the sake of illustration and to Which I do not Wish to be understood as limiting inyself, cl, indicates a standard upon which is revolubly mounted a bed a", having formed thereon or secured thereto a stationary carrier a2. A movable carrier as is arranged to slide in a guideway in the hed, movement being imparted thereto by any suitable'ineans, such as a hand-Wheel b, rotating pinions o', which engage raclnbars b2, connected to the stationary carrier. Upon the carrier are pivoted heads c c', which maybe adjusted to any desired angle and upon which are placed Wipers for automatically wiping the edges of the upper over the sole of the last at the toe and heel, and bands for clamping the upper to the last during the wiping operation.

Mounted upon the bed is a standard a4, which may be adj usted vertically by any desirable adjusting means and Which is formed or provided with a spherical or ball-like end d5. A cap a6, having a socket to receive the spherical end d5, is placed upon the standard and has a convex upper surface to receive the top of the last When the latter is in the machine. This standard relatively to which the last is forced horizontally coacts with the curved top thereof in such Way as to jack the last vertically against the wi pers both at the toe and at the heel.

Referring to Figs. 2 to 6, inclusive, and to Fig. 12, the head c has pivoted thereto by a pivot CZ a tilting bolt d', having a iiange d2 and a threaded portion d3. Fivoted tc the outer end of the head by a screuT d* in axial alinenient with the pivot d for the bolt d is a cross-har d5, the upper edge of the said cross-bar d5 being in alineinent With the upper edge of the flange d2. Resting upon the iiange d2 of the bolt d is a top plate c, which is provided at its rear edge with a depending flange e', resting upon the crosabar d5, said flange e being formed upon the top plate e or else secured thereto hy screws e2, as shown. The top plate is provided with an aperture adequate to receive the bolt d', to which it is rigidly secured by a nut d and a Washer di. By reason of the pivot d and the pivotscreuT dL being in alinenlent and being arranged in the central longitudinal line of the head the plate e may be tilted, as shown in Fig. 6, relatively to the stationary head c.

Projecting downwardly from the sides of the top plate e are guide-bars e2 e2, having inwardly-projecting flanges e3, and inserted between said flanges and the under face of the top plate e are wipers f f and the carriers g g for the band h. The said band-carriers are similar in shape, as shown in Fig. 14, and have their outer edges g resting against the guide-bars e2. Their inner edges are cut away to form a curve, so as to receive between them the heel of a last, and they are provided at their edges with upwardly-projecting strengthening curved lianges g2, to which the band is secured. This band may be formed of any suitable flexible material, although l prefer leather, and operates to bind the upper firmly to the end of the last. It projects downward below the iianges g2, as shown in Fig. 3, and it serves to unite the two carriers g g flexibly together at the point 2, as' shown in Figs. l2 and 14. It will be observed that the edges g' g are curved, as at 3 3, the curves being arcs of a circle struck from the point 2, the diameter of the circle being equal to the distance between the guidebars e2. The flanges g3, which are continuations of the flanges g2, abut against movablepins g4, passed horizontally through the head c. Between the flanges g5 on the pins and a bar gs, which is secured in a slot in the head, are placed springs g7, encircling the pins g4, so that the ends of the pins are held yieldingly in contact with the band-carriers, each bearing against only one of the carriers g, so that the latter may be moved relatively to each other, as desired.

Inserted between the top surfaces of the carriers g and the under surface of the plate e are the two loosely-mounted wipers ff. They are similar to each other in plan view, each having its inner edge f curved to correspond to the heel of a last. They are cut away, as at f2, so as to escape the bolt d' and its ilange d2, and they rest at their rear ends upon the cross-bar d5. They are closely conlined between the guide-bars e2 e2 and are each provided with a recess having a curved edge 5, which is an arc of a circle struck from the point 4 and whose diameter is equal to the distance between the guide-bars e2, said point 4 being the meeting-point of the front inner corners of the wipers. The rear inner edges are inclined and diverging and are formed with rack-teethf3, with which two intermeshing pinions f4 f4 engage, said pinions being mounted to turn loosely upon studs f5, projecting upwardly from the head c. The wipers are provided with rearwardly-projecting pins f6, connected by a -strong tensionspring f7, and they are also provided with downwardly projecting studs f8, against which the rear edges of the carrier g g for the p band may engage, as shown in Figs. 5 and l2, to limit'the movement of the wipers over the heel. Now it will be seen that the upward and rearward pressure of a last against the wipers will cause a rearward movement of the wipers, whereupon the inclined edges will be separated by the pinions and the curved edges f f of the wipers will be swung toward each other about the point 4, which point moves in a straight line toward the pivot d', the guide-bars e2 coacting with the curved edges 5 of the wipers in holding the corners of the wipers together at they said point 4, so that the said corners are always in contact. The wipers being engaged in the rear of the point 4 by the pinions f4f4, they must necessarily move in unison, for the swinging movement of one wiper will cause a simultaneous corresponding movement of the other.

The carriers for the band h, although entirely disconnected from the wipers, swing toward each other about the point 3, so that the band lirrnly clamps the upper against the heel at all points along its length.

The curved edges 3 3 of the carriers cooperate with the guide-bars e2 in holding the corners of the carriers together at the point 3 as the point moves in a straight line toward the pivot-bolt d'. Besides operating as a clamp for the upper, the band and its carriers act as stops in limiting the movement of the wipers inward over the sole of the last, since the flanges g3 of the carriers engage the stops or pins f8 of the wipers, the said pins being normally a short distance from the curved edges f of the wipers. The springs f7 and Q7 immediately return the wipers and `the band-carriers to their normal positions as soon as the pressure of the last upon the bandy and the wipers ceases.

Springs t t are secured to the head c and IOO bear upwardly against the band-carriers g g to assist the flanges e3 of the guide-bars c2 in holding the said carriers and the wipers against the top plate e. By reason of the said top plate being pivoted to swing upon a substantially horizontal axis the wipers and the band are adapted to accommodate themselves to a last having the plane of the sole at the toe at an angle to the plane of the sole at the heel, so that when the last is pressed against the band and the wipers not only do the latter automatically adjust themselves, but they automatically operate-independently of any power devices.

Now, 'referring to Figs. 7 to 1l, inclusive,

-and to Fig. 13, I have shown the pivot-boltj,

which corresponds to the bolt d', as being rigidly secured in the head c instead of tilting, it being provided with a flange j', additional to the flange j?, for this purpose. The top plate k is pivoted on the bolt j by a nut js and washer (i4, so that the plate is capable of swinging horizontally or in planes parallel to the upper surface of the head c'. The wipers ZZ have front inner curved edges l to lit over the toe of the last and are provided with the inwardly-projecting lugs Z2 to rest upon the last when the latter is first placed in the machine. They are cut away, as at Z3, to escape the bolt y',and they are provided on their inner edges IIC flange to extend into a groove m in a disk coupler m, which is placed between them so as to couple them together and cause their movements to be simultaneous, besides providing a continuation of Athe curved edges l l' of the wipers. The curved edges 7 7 of the recess a in the sides of the wipers are arcs of a circle struck from the point S, which is the center of the coupler m, the diameter of the circle being equal to the distance between the guide-bars 7c k', extending downward from the top plate k. That portion of the ilange m of the coupler m which is exposed between the corners 9 9 of the wipers forms a continuation of the curved edges Z of the wipers unless the wipers are in such position that the corners abut.

Instead of providing pinionsjf5 to operate the wiper l'. mayemploy rollers n n, loosely mounted on studs fn n', projecting upward from the head c', and the wipers are provided with the inclined edges l0 10, which coact with the rollers in forcing the outer end of the wipers outward and the front ends thereof inward when the said wipers are moved longitudinally to the rear. Thus by providing the coupler which engages the two wipers l am l enabled to dispense with the pinions and the gear-teeth and to employ the rollers and the straight inclined edges for separating the rear ends of the wipers.

The spring o, having its ends connected to pins o o', projecting rearward from the wipers, is provided for returning the wipers to their inoperative positions when pressure upon the same ceases.

Below the wipers are placed the carriers p p for the band q, which are constructed substan tiallyas hereinbefore described, and they bear against the independentlymovable yielding pins p' 2i', passing through apertures in the head c. The head is stationary against rotation, while the cap and the wipers are free to rota-te about the pivotj, so that the said wi pers will. automatically adapt themselves to a last having the median line of the toe inclined to the median line of the heel, as shown in. Fig. 13, and as the pins p are independent the carriers and the band also automatially adjust themselves to the last, as they are free to slide between the wipers and the springs r fr, which hold them against the under faces of the wipers. The band and the carriers are entirely independent of the wipers in this case, nor are there projecting stop-pins carried by the wipers to be engaged by the said carriers to limit the movements of the wipers. Then upward and rearward longitudinal pressure is exerted against the band and the wipers, the wipers are forced rearwardly and the curved edges move toward each other over the sole of the last, said wipers swinging about the point S and being held inward by the engagement of the curved edge 7 with the guide-bars 7.a.

In nsing'the machine for lasting the last is inverted and is placed between the carriers,

with its top resting upon the standard. Then by means of the hand-wheel the movable carrier is forced toward the stationary carrier, with the result that the last is jacked vertically against the wipers both at the toe and the heel. The longitudinal pressure against the said wipers and the bands causes the bands to firmly embrace the ends of the last to clamp the upper thereagainst, and it causes the wipers to swing automatically over the edges of the upper and the sole of the last to draw the said edges taut. As I have before stated, the Wipers and the band are independentof each other and are not connectedl together, and although the wipers swing about a given moving point they too are disconnected and are pivoted neither to each other nor to the head of the carrier.

Although I prefer to employ the movable band and its carriers, yet they are not absolutely necessary to the lasting operation, as the wipers are automatically operated without them by the engagement therewith of the last and upper.

By mounting the wipers on one of the carriers to tilt vertically or perpendicularly to the head and the wipers on the other head so as to swing in planes parallel to the head they automatically adapt themselves to a last of any shape or size, whether the plane of the sole at the heel be at an angle to the plane ot the sole at the toe or whether the median line of the last at the toe be at an angle to the median line thereof at the heel. Thus the upper is drawn taut both at the toe and the heel merely by causing the two sets of .wipers to approach each other, since the last sliding on the standard is jacked vertically to pro- Kmi IOC

vide thenecessary upward pressure upon the wipers.

In Fig. 13 l have shown by full and by dotted lines how the band and its carriers automatically adapt themselves to differentlyshaped lasts, although the head upon which they are mounted is relatively stationary. This is accomplished by placing the carriers in guides on thel head to slide freelyv and loosely and by placing the spring-pressed pins or fulcrums on both sides of the central line of pressure, so that the two carriers will, by the wedging pressure of the toe between said pins or fulcrums, be swung toward each other to clamp the band against the upper and last.

The band maybe formed in two independent halves s s, each half being secured to one of the carriers, as shown in Fig. l5, and by reason of the curved edges 7 engaging the guide-bars 7a the ends 2 of the said halves s s do not separate, but remain in contact, so as not toinjure or mar the shoe. Hence, though the wipersand the band are independently movable and are independently mounted upon a support, they are automatically operated by the engagement of a last therewith, and both automatically adapt themselves to different shapes and sizes of lasts.

Both the toe and the heel wipers are cou- IIO pled together to cause their movements to be simultaneous or in unison. The coupler for the toe-wipers yperforms two functions, for in addition to compelling them to movein unison and to the same extent it forms a continuation of the operative edges thereof,being also flush with their under or operative surfaces, so ask to prevent the upper from being dented or marred in any way, and the coupler for the heel-wipers-z'. e., the rack-teeth vention. i It is evident that the supports for the wipers and the band-carriers may bek constructed to meet any particular requirements as to shape and lightness and may be changed from their present locations.

In Figs. 16 to 19, inclusive, I have illustrated the toe-wipers as being arranged to operate without a coupler in the form of a disk, in which case the meeting inner corners of the wipers always remain in contact, heilig similar in this respect to the heel-wipers before described. The two wipers t t are placed between the 'cap-plate u andthe head e and are connected at their rear ends by the spring fw. For the purpose of providing wedges for separating the rear ends of the wipers the wipers are formed with diverging slots t t', into which project pins u' u', depending from the cap-plate u, and for holding the corners in contact at the point 15 the plates are formed with slots t2 t2 to receive pins u2 u2, projecting down from the said cap-plate. Thus it will be seen `that the wipers when operated by the engagement of a last therewith will have their operative edges automatically swung toward each other. A coupler consisting of a curved baris placed in a groove in the wipers to cause the wipers to move in unison. The curve of the coupler and the groove is the arc of a circle struck from the point 15 as a center, since the wipers swingl about that point. Thus it is evident that the wipers may be formed in many ways for performing the same functions.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1.
